Abstract

Emulsifications process can positively contribute to increasing oil recovery during the extraction process. However, emulsion instability can cause phase separation and reduce production. This phase separation causes oil and water to separate, hindering the flow of the mixture and reducing the ability to remove oil from the reservoir. To overcome this problem, the emulsification process requires the addition of an emulsifying agent and energy to stabilize the mixture. In this study, emulsification was carried out with NaCl, to increase the interaction between the water and oil phases, with the hope of increasing emulsion stability and reducing the possibility of separation. This study analyzed the effect of water chemistry with NaCl, oil-to-water volume ratio, and stirring time on the stability of the emulsion resulting from the emulsification process. The aim was to determine how these factors affect emulsion stability, where emulsion stability is measured by its ability to withstand separation between the oil and water phases. Based on the results of the bottle test, the addition of NaCl with a concentration of 5,000 ppm to water-in-oil (W/O) emulsions tends to be more effective in increasing emulsion stability and producing a longer separation time compared to the addition of 10,000 ppm.
